Question

Help in Algebra 2 having trouble Factoring
Let f(x) = 4x - 7 and g(x) = 2x - 3. Find (f*g)(4)

a. 9
b. 13
c. 5
d. 15

Answer 1

f(x) * g(x)= (f*g)(x)
(4x-7)(2x-3) = 8x^2 -12x -14x +21
= 8x^2 -26x +21
now(f*g)(x) = 8x^2 -26x +21
replace x with 4 and get your final answer
and show me what u get

Answer 2

i got 45

Answer 3

yes u are correct
let me review it again

Answer 4

(f*g)(x) = f(g(x))
= f(2x-3)
= 4(2x-3)-7
= 8x -12 -7
= 8x - 19
now replace x by 4 in
(f*g)(4) = 8(4) -19
= 32-19
= 13 is correct answer
